The Effects Of Piping Design On The Measurement Accuracy Of Meters In Large System Applications
Author(s): William J. Kolb I I IAbstract/Introduction:Over the past year or so, we have seen a number of existing fuel delivery gantry systems in various parts of the world that have been exhibiting some extreme transient pressure conditions. Some of these systems also have shown advanced corrosion within the piping system. We were drawn to these systems because of meter and/or valve performance was not acceptable.Go to Download PageEmail ReferenceDocument ID:

Recent Research Results In Wet Gas Metering
Author(s): David Stewart, David Hodges, Gregor BrownAbstract/Introduction:Wet gas metering is being used increasingly in economically marginal fields, reducing the capital costs by allowing several small fields to share common platform infrastructure. The development of reliable wet gas meters is a key requirement in the oil and gas industry at present. Such meters should be able to measure both the gas and liquid flowrates if desired. However, in some cases the liquid flowrate is not important, requiring only the gas flowrate to be measured accurately.Go to Download PageEmail ReferenceDocument ID:

Multiphase Flow Metering - Practical Requirements And Experience From Field Applications
Author(s): Andrew HallAbstract/Introduction:Oil producers have always had a requirement for metering of multiphase production from wells and this has traditionally been performed by separation of the well stream and metering of the separated gas and liquid rates, either by fixed or portable well test units. In recent years, developments of technology have opened up the possibility of multiphase metering of unseparated well streams. Several commercial systems are available and some have now been in operation for several years.Go to Download PageEmail ReferenceDocument ID:

The Universal Applicability Of The Non-Intrusive Widebeam Ultrasonic Flowmeter Technology To Both Oil And Gas Flow Applications
Author(s): Joe Baumoel, Robert SchaeferAbstract/Introduction:Gas and Oil are quite different from each other in their physical, chemical, and ultrasonic properties. Nevertheless, it has been found that each fluid state is able to utilize the pipe wall as a Sonic Waveguide to permit highly accurate and reliable non-intrusive flowmetering. This paper explains the similarities and difference between liquid and gas ultrasonic metering and provides field and laboratory test data that testifies to the ability of WideBeam Clamp-On Transit-time Ultrasonic flowmeters to provide highly accurate Checkmetering and Custody Transfer performance in both application classes.Go to Download PageEmail ReferenceDocument ID:

Performance & Diagnostics Of Usm In Natural Gas Measurement
Author(s): Kevin Chin, Lim Song Hau, Ong Min SingAbstract/Introduction:For the last 5 years, customers in Asia Pacific have installed more Gas Ultrasonic meters for custody transfer application. Tracing back to the early installations, the meters were installed just like any other meters. There was not much performance or diagnostic information given to flow computers or SCADA/DCS. Even when the diagnostic information is available, access to this information requires a lot of work. However, as time passed, customers were educated on the various diagnostic features available within the meter and, hence, with improved diagnostics built in, the monitoring of Ultrasonic meters (USM) can be done without the need to leave the control room.Go to Download PageEmail ReferenceDocument ID:

Improving Flow Allocations By Using Meters Uncertainties
Author(s): Hoi Yeung, Sulaiman Al-RoumiAbstract/Introduction:Despite the huge amounts of money companies spend to improve their flow measurements they could get limited reward if their bill comes as a result of an improper allocation system. Conventional proportional allocation (PA) method has been used widely due to its familiarity and simplicity however, it may distribute the measurement imbalance in an unfair and improper manner due to its neglect of the uncertainty of the systems meters.Go to Download PageEmail ReferenceDocument ID:
